A monthly gauge of construction sector activity. The CIPS PMI asks executives in the construction sector about the state of business and the current level of purchasing. These managers are tasked with gauging future construction demand, and adjusting orders for materials accordingly. The PMI summarizes the opinions of these executives to give a picture of the future of the construction sector. A higher PMI indicates that materials purchases are increasing and that the economic outlook is positive. Alternately, a lower PMI means orders for materials are down and the future outlook is less favorable. By nature, the figure is very sensitive to the business cycle and tends to match growth or decline in the economy as a whole.
